ARTHUR JONES, OF CHICAGO, ILLINOIS.

HAND-GRENADE FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 318,909, dated May 26,1885.

Application filed September 15, 1884.

To oiZZ whom it may concern.-

Be it known that I, ARTHUR J ones, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hand-GrenadeFire-Extinguishers, of which the following is a specification, to wit:

This invention relates to an improvement in a hand-grenadefire-extinguisher; and it consists in the peculiar construction of thesame, whereby its breakage at the proper moment is insured,substantially as will be hereinafter more fully set forth and claimed.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe mydevice, referring to the accompanying drawings, in which- Figure l is aside elevation, and Fig. 2 a bottom view, of my grenade, and Fig. 3 adetail view of one of the parts of which it is composed.

In the construction of hand-grenades for fire-extinguishers it has beenfound that a certain amount of strength is necessary to retain the gascontained in the bottle, and when this is obtained there is danger ofthe bottle not being broken when thrown upon a lire. This difficulty Iobviate as follows: The grenade is made in two or more separate parts, aa, each of which forms a separate receptacle for holding theextinguishing chemicals or gas. These parts are formed with a neck orextension, at, having one or more llat sides, as shown, and the mainbody a of the receptacle is of the same form in cross-section as theextension, but is set at a slight angle therewith, as shown in Fig. 3.The shanks of two, three, or more of these receptacles are placedtogether and secured by a band, I), of metal or other suitable material,lying in a circumferential groove, 1), in the extension,as shown. Bythis it will be observed that while the necks are bound closely togetherthe shouldered or inclined bodies lie a slight distance away from eachother, and when dropped the two parts spring together and are broken.

(No model.)

The device is herein represented as formed in three parts in the shapeof an ordinary bottle; but I do not wish to confine myself to this formor number of parts, as this may be varied to suit, so long as it is madeof fragile material and of such shape that while one part of eachportion is held closely against the other, the other part of each standsawaya sufficient distance to give it room to spring when struck andinsure its breaking.

\Vhile the device will of course be shivered to pieces when struck withsufiicient force, it will be found that a very slight blow is allthat isnecessary to spring its main body aside and snap it at the point ofsecuring to the other parts, which add their weight to the shock andinsure this result.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The herein-described hand-grenade, con sisting of a glass bottle orreceptacle having one or more flat sides and formed with a neck or shankprojecting outward from the Hat side at a slight angle with the mainbody and of the same form in cross-section, substantially as and for thepurpose set forth.

2. In a handgrenade, the bottle a, having an extension or neck, a,formed with a circumferential groove, in combination with asecuring-band, b, secured in said groove, the main bodies of thereceptacles having one or more flat sides and formed with their necks orshanks projecting outward from the fiat side at a slight angle with themain body, whereby the necks are held together compactly while the mainbodies are slightly separated to facilitate breaking, substantially asshown and described.

In testimony whereof I aliix my signature in presence of two witnesses.

ARTHUR JONES.
